[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 3The diagram illustrates a snap ring assembly device, where the snap ring conveying groove, spring conveying groove, and groove cover on the central assembly platform are not shown. The device includes a base cabinet 1, a snap ring conveying mechanism, a spring conveying mechanism, and a central assembly platform 2. The base cabinet integrates an electrical control system. The snap ring conveying mechanism, spring conveying mechanism, and transition block mechanism are all fixedly mounted on the base cabinet and controlled by the electrical control system. In this embodiment, to facilitate snap ring conveying, the snap ring conveying mechanism includes a snap ring vibratory feeder 3, a snap ring conveying groove 4, and a snap ring pushing mechanism. The snap ring vibratory feeder is fixed to the base cabinet. On the side edge of the cabinet, the snap ring conveying groove is connected between the discharge port of the snap ring vibratory plate and the central assembly table. The snap ring pushing mechanism is installed on the bottom cabinet on the side of the central assembly table and is used to push the snap rings conveyed by the snap ring conveying groove from the feeding position of the central assembly to the assembly position. In actual application, the snap ring conveying groove is provided with a groove cover and a straight vibration seat 5 at the bottom to improve the stability during vibration transmission. After the snap ring 27 vibrates and outputs from the vibratory plate, it enters the snap ring conveying groove and is then conveyed to the feeding position of the central assembly table in sequence. Then, it is pushed to the assembly position by the snap ring pushing mechanism for assembly.

[0021] In this embodiment, to facilitate the conveying of spring pieces, the spring piece conveying mechanism includes a spring piece vibrating plate 6, a spring piece conveying groove 7, and a spring piece pushing mechanism. The spring piece vibrating plate is fixed on the other side of the base cabinet. The spring piece conveying groove is connected to the discharge port of the spring piece vibrating plate and the middle assembly table. The spring piece pushing mechanism is used to push the spring pieces output from the spring piece conveying groove from the feeding position of the middle assembly table to the assembly position. Similarly, the spring piece conveying groove is provided with a groove cover and a straight vibration seat at the bottom to improve the stability during the vibration output process. After the spring piece 28 vibrates and outputs from the vibrating plate, it enters the spring piece conveying groove and is then conveyed to the feeding position of the middle assembly table in sequence. Then, it is pushed to the assembly position by the spring piece pushing mechanism for assembly.

[0022] In this embodiment, to facilitate the transmission of the spring and the snap ring, the central assembly platform is configured as an L-shaped block, including a long block and a short block. The long block is positioned along the rear side of the base cabinet, and the short block is positioned near the snap ring pushing mechanism. A first strip groove 8 is formed on the upper side of the short block, with its two ends connecting to the two side edges of the block. A strip main groove 9, which is connected to and perpendicular to the first strip groove, is formed on the upper side of the long block, with its two ends also connecting to the two side edges of the block. The internal structure of the strip main groove fits the shape of the snap ring, thus facilitating the stable transmission of the snap ring within it. A spring groove 10, parallel to the strip main groove, is formed on the upper side of the tail of the long block. A second strip groove 11, perpendicular to and connected to the spring groove, is formed on the upper side of the block at the tail of the spring groove. Similarly, to facilitate the transmission of the spring... The internal structure of the second strip groove fits into the spring sheet structure, thus facilitating the transmission movement of the spring sheet. The tail end of the second strip groove connects to the main strip groove. The connection points between the main strip groove and the first strip groove, and between the second strip groove and the spring sheet groove, are the feeding positions for the retaining spring and the spring sheet, respectively. The connection point between the main strip groove and the second strip groove is the assembly position. Therefore, the retaining spring will first slide in the first strip groove to the feeding position on the left side of the main strip groove, and then be pushed to the assembly position in the middle of the main strip groove. The spring sheet will first slide in the spring sheet groove to the feeding position of the second strip groove, and then be pushed to the assembly position of the main strip groove to assemble with the retaining spring. In addition, in practical applications, to improve transmission stability, groove covers are provided on the upper parts of the first strip groove, the second strip groove, the main strip groove, and the spring sheet groove.

[0023] In this embodiment, to facilitate the movement of the retaining ring within the slot, the retaining ring pushing mechanism includes a first retaining ring pushing cylinder 12, a first retaining ring push rod 13, a second retaining ring pushing cylinder 14, and a second retaining ring push rod 15. The first retaining ring pushing cylinder is fixed to the base cabinet at the end of the short block. The first retaining ring push rod is connected to the piston rod end of the first retaining ring push rod and is placed within the first strip groove, allowing it to slide freely relative to the first strip groove. The second retaining ring pushing cylinder is fixed to the outer side of the corner of the L-shaped block. The second retaining ring push rod is connected to its piston rod end and is placed within the left side slot of the main strip groove, allowing it to slide freely. The first retaining ring push rod and the second retaining ring push rod cooperate with the first strip groove and the main strip groove, respectively, thus effectively and stably pushing the transmission movement of the retaining ring. Furthermore, in this embodiment, to facilitate the stable movement of the spring piece within the slot, the spring piece pushing mechanism includes a first spring piece pushing cylinder 16, a first spring piece push rod 17, a second spring piece pushing cylinder 18, and a second spring piece push rod 19. The first spring piece pushing cylinder is fixed to the base cabinet at the end of the long block. The first spring piece push rod is connected to the piston rod end of the first spring piece push rod and is placed in the spring piece slot, allowing it to slide freely relative to the spring piece slot. The second spring piece pushing cylinder is fixed to the inner side of the corner of the L-shaped block. The second spring piece push rod is connected to its piston rod end and is placed in the second strip groove, allowing it to slide freely. The first spring piece push rod pushes the spring piece into the strip groove, and then the second spring piece push rod pushes the spring piece into the assembly position of the main strip groove for assembly. In this embodiment, to facilitate the discharge of the retaining spring and the spring sheet, a first opening corresponding to the outlet of the retaining spring conveying groove is provided on one side of the first strip groove, and a second opening corresponding to the outlet of the spring sheet conveying groove is provided on one side of the spring sheet conveying groove. In addition, to facilitate the movement of the retaining spring and the spring sheet, a retaining groove 20 corresponding to the first opening is opened on the upper side of the end of the first retaining spring push rod. Therefore, in the initial state, the retaining groove on the first retaining spring push rod corresponds to the first opening. After the retaining spring enters the first opening from the outlet of the retaining conveying groove, it will directly enter the retaining groove. Then, the first push rod is controlled to extend to the strip main groove, so that the retaining groove corresponds to the groove opening of the strip main groove. Then, the retaining spring on the retaining groove can be pushed out of the retaining groove and moved to the assembly position in the middle of the strip main groove by the second retaining spring push rod, thereby completing the movement process of the retaining spring. Then, the first retaining spring push rod returns to the initial position to push the next retaining spring. This cycle repeats to complete the continuous movement process of the retaining spring.Similarly, a spring mold groove 21 corresponding to the spring slot and matching the shape of the spring is also opened on the upper side of the end of the first spring push rod. Therefore, in the initial state, the spring mold groove on the first spring push rod corresponds to the second opening. After the spring enters the second opening from the spring conveying groove outlet, it will directly enter the spring mold groove. Then, the first spring push rod is controlled to extend and push the spring into the second strip groove. Then, the spring on the slot can be pushed out of the spring mold groove and moved to the assembly position in the middle of the strip main groove by the second spring push rod, thereby completing the movement process of the spring. Then, the first spring push rod and the second spring push rod return to the initial position to push the next spring. This cycle repeats to complete the continuous movement process of the spring.

[0024] In this embodiment, to improve the stability of the snap ring transmission, a transition block mechanism is provided above the central assembly platform, including a support frame 22, a cylinder plate 23, a cylinder 24, and a transition block 25. The support frame is vertically supported and fixed on the base cabinet on the side of the central assembly platform. The cylinder plate is horizontally fixed to the upper end of the support frame, and the cylinder body is fixed to the upper side of the cylinder plate. The piston rod passes downward through the cylinder plate and connects to the upper end of the transition block. An opening is provided at the end of the second strip groove for the lower end of the transition block to extend and retract vertically. A die opening 26, consistent with the shape of the snap ring, is provided on the lower end of the transition block for the snap ring and the second snap ring push rod to pass through. Further, to improve assembly accuracy, an elastic brake pad 29 is provided on the side wall of the assembly position of the main strip groove of the central assembly platform. The elastic brake pad is located inside the groove wall and can elastically extend and retract horizontally relative to the vertical groove wall. Figure 3 As shown in the figure, the rear part of the central assembly platform (with the main strip groove as the boundary) is not shown. Therefore, when the retaining spring moves in the main strip groove, the cylinder is first controlled to drive the transition block to move downward, thereby causing the die opening to move down and making the front wall of the assembly position of the main strip groove a flat wall surface. Then, the retaining spring is pushed to the assembly position and clamped by the brake pad on the rear side of the assembly position, thereby improving the assembly accuracy and stability. After the retaining spring moves into place, the cylinder drives the transition block to move upward, causing the die opening to move upward until it corresponds to the front and rear of the assembly position. Then, the spring is pushed through the die opening and into the assembly position, which facilitates the transition and transmission of the spring. In practical applications, in order to facilitate the movement and transmission of the spring, the front end of the second spring push rod is provided with an opening that matches the spring die groove. Therefore, it is easier to push the spring on the spring die groove into the second strip groove and continue to push the spring through the die opening of the transition block into the assembly position.

[0025] In the actual assembly process, the snap ring is fed into the first strip groove by the vibratory feeder through the conveying groove. Then, the first snap ring pusher is controlled to drive it into the feeding position of the main strip groove. Then, the cylinder is controlled to drive the transition block to move down and misalign. Then, the second snap ring pusher is controlled to push the snap ring into the assembly position in the middle of the main strip groove and be clamped by the brake pad. The spring is fed into the spring slot by the vibratory feeder through the conveying groove. Then, the first spring pusher is controlled to drive the spring into the feeding position of the second strip groove. Then, the cylinder is controlled to drive the transition block to move up until the die orifice corresponds to the assembly position of the main strip groove. Then, the second spring pusher is controlled to push the spring from the second strip groove through the die orifice at the lower end of the transition block and into the assembly position of the main strip groove to assemble with the snap ring to form the assembled snap ring product 30. After the assembly is completed, the above process is repeated to assemble the next product. The previous product will squeeze the next product out of the assembly position. In this way, they accumulate in the right groove of the main strip groove until they are squeezed out of the discharge port on the right side of the main strip groove, thus completing the discharge process.

[0026] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
